VALVE ACTUATED SWITCH Filed Sept. 24, 1928 2 Sheets-Sheet '2 I Imlawnmiu INVENTOR ATTORNEY Patented June 3, 19130 UNITED STATES PATENTOFFICE WALTER J. MACKEY, OF DETROIT, MICHIGAN sir VALVE-ACTUATED SWITCHApplication filed September 24, 1928. Serial No. 308,109.

This invention relates to igniting devices, and its general object is toprovide an unproved switch for ignitors for fuel burners and the likethat lights the fuel simultaieously with the opening of the controlvalve )f the fuel pipe line to the burner.

One of the important objects of the invention is to provide a valveactuated switch that can be easily installed on the valve of a )urner soas to be operated by said valve when the latter is opened, but does notin any way interfere with the proper operation thereof.

A still further object of the present invention is to provide a deviceof the character set forth, that is extremely simple in construction,inexpensive to manufacture and install, and efiicient in operation andservice.

This invention also consists in certain other features of constructionand in the combina- 2 tion and arrangement of the several parts. to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a side elevation of my improved igniting device applied to avalve.

Figure 2 is a sectional view taken approximately on line 22 of Figure 1.

Figure 3 is a sectional View taken approximately on line 33 of Figure 2.

Figure 4 is a sectional view taken approximately on line 1- 1 of Figure1.

Figure 5 is a perspective view of the upper plate which forms a part ofthe contact-breaking means of my device.

Figure 6 is a similar view of the lower plate which cooperates with theupper plate.

Referring to the drawings in detail, the reference numeral 1 indicatesthe core of a valve for controlling the supply of fuel to a gas burnerand the like, and 2 indicates the casing for the core which as clearlyshown in Figure 3 has extending from diametrically opposite sidesthereof nipples 3 that are threaded for the purpose of being disposed inthe fuel supply pipe line for a burner or the like as will be apparent.

The casing is reduced at its upper end to provide a shoulder, andsecured to the reduced portion through the medium of a screw 1 is asleeve 5 which has formed therewith and extending therefrom asubstantially rectangular shape projection 6 provided with alongitudinally disposed groove 7 and an outwardly inclined top 8.

Arranged for slidable movement in the groove 7 as clearly shown inFigure 3 is the bottom plate 9 that is provided with a longitudinallydisposed slot 10 which accommodates the head 11 of a bolt 12. The head11 is in the form of abearing for slidably receiving the bottom plate 9and is formed with a cap for engagement with the plate as shown. Thebolt 12 is passed through aslot 13 formed in the projection 6 and isadjustably received in the slot 13 by a nut. The forward end of theplate 9 is reduced and formed with and rising from said forward end is alug 1 L having a beveled upper side as best shown in Figure 3.

Mounted for slidable movement on the inclined top 8 of the projection 6is an upper plate 15 which cooperates with the lower platethrough theinstrumentality of a lug 16 that depends from one end of the upper plate15 and is arranged for engagement with the lug 1 1 during certainpositions of the plate 15. The upper plate 15 is formed with a centrallydisposed opening to accommodate the shank of a headed stud 17 andsecured to the stud 17 is one end of a link 18 while the opposite end ofsaid link is pivotally secured to a stem bracket 19 that is fixed in thereduced upper end of the core 1 whereupon movement of the core throughthe instrumentality of its handle for disposing the bore of said core inregistration with the bores of the nipples 3 will operate my device in amanner which will be presently described.

Secured to the sides of the projection 6 are strips 20 having flanges 21bent at right angles to the bodies thereof and overlying the upper plate15 to hold the latter in op erative position with respect to theinclined top.

(Iii

ranged in the path of the last mentioned lug.

In a valve-actuated switch, a sleeve, a projection formed with saidsleeve and being provided with a groove with a slot communicating withsaid groove, a slotted plate mounted for slidable movement in saidgroove, means passing through the slots and slidably securing said platein said groove, a second plate mounted for slidable movement at aninclination, a movable stem bracket, and a link between the stem bracketand inclined plate for moving the latter, lugs formed with said platesand disposed in cooperative association with respect to each other.

6. In a valve-actuated switch, a pair of sliding plates, one of saidplates being inclined, lugs formed with said plates and being arrangedwhereby the lug of one plate engages the lug of the other plate for moving said last mentioned plate, spring means for urging said lastmentioned plate in a di rection opposite from that in which it is movedby the lugs, a spring pressed plunger bolt arranged in the path of thelug of the last mentioned plate, and the lugs being formed to cooperatefor carrying the last mentioned plate to a position to cause the lugEhereor to momentarily contact the plunger olt.

In testimony whereof I afiix my signature.

WALTER J. MACKEY.
